WhatsApp: +86 18203695377Gasification Introduction Gasification is a technological process that can convert any carbonaceous (carbonbased) raw material such as coal into fuel gas, also known as synthesis gas (syngas for short).
WhatsApp: +86 18203695377Coal Gasification Process. During gasification, oxygen and steam (water vapour) are blown through the coal while it is still being heated (and in a few cases pressurised as well). "Allothermal" refers to a procedure in which the coal is heated by external heat sources, whereas "autothermal" refers to a process in which the coal is ...

WhatsApp: +86 18203695377In industrial chemistry, coal gasification is the process of producing syngas —a mixture consisting primarily of carbon monoxide (CO), hydrogen ( H2 ), carbon dioxide ( CO2 ), methane ( CH4 ), and water vapour ( H2O )—from coal and water, air and/or oxygen. Historically, coal was gasified to produce coal gas, also known as "town gas".

After the oil crisis in 1973, there was an interest to develop new forms of energy that could offer an alternative to the use of oil; mainly focused on the production of gas ...
WhatsApp: +86 18203695377Fluidizedbed gasifiers suspend feedstock particles in an oxygenrich gas so the resulting bed within the gasifier acts as a fluid. These gasifiers employ backmixing, and efficiently mix feed coal particles with coal particles already undergoing gasification. To sustain fluidization, or suspension of coal particles within the gasifier, coal of ...

WhatsApp: +86 18203695377The process involves gasification of coal, which in turn will produce synthetic gas (a mix of CO+H2). The synthetic gas can be liquefied to its fuel equivalent in presence of cobalt/ironbased catalysts at higher pressure and temperature. However, liquefied coal emits twice as much CO2 as burning oil. It also emits a large volume of SO2.
